Yeah, I thought it looked familiar. :-/  Sorry for not digging into it 
deeper myself before reporting, and thanks for looking into it. I'm 
having massive problems with -current atm, and I'm trying to do a binary 
search to find out when they started in the middle of also trying to get 
$REALWORK done.

Since I was just able to trigger the problem I'm seeing without heavy 
access on my ext2fs partition, I'm thinking that what I might do is back 
all of my sources up to the point in the binary search that I'm testing 
but then 'cd /sys/fs/ext2fs && svn up', does that sound safe?
